NOTE: The fax/modem board uses x2
technology. An x2 product is capable of 56 Kbps
(52 Kbps in the U.S.). However, the download
speeds you experience may go lower due to
varying line conditions. Uploads from end user to
service provider travel at speeds up to 28.8
Kbps. An x-2-compatible analog phone line and
an x2-capable service provider are required for
high-speed downloads. See
for details.
